Raise your hand if, as a kid, you envisioned someday flying around like one of the Jetsons in your very own airborne car. You have lots of company. But is that really ever going to happen?

Not likely, say experts–there are just too many hurdles to jump. But the concept of daily travel by air may not be so farfetched, and more than 70 companies are currently working on developing air taxis, which are along the same concept of a transportation network company vehicle only above the road instead of on it. Several regulatory agencies, including in Europe and Japan, are working on the legal frameworks necessary to let air taxis fly in heavily regulated airspace, and some companies–including Uber Elevate–say they’ll have the flying shared rides in the air by 2023.

What’s all this mean to parking and mobility? Plenty. Check out the breakdown on Bloomberg Businessweek.
